UBC module

Seismic loading per Uniform Building Code 1997

Program features

The UBC module determines the following forces and moments for columns (as well as vertical storage tanks, chimneys, etc.) caused by earthquakes:

Shear load at vessel / construction head

Overturning moment at base

Moment in arbitrary height X

The calculation is performed dependent on geometrical data, operational mass and material strength as well as the characteristic values of seismic zones and soil characteristics. The results of the calculation are proof of a sufficient dimensioning of the mounting at the foundation.

Additionally the required wall thickness at the lower part of the apparatus or the skirt is calculated and compared to the actual wall thickness.
